The Rossa Monza Corza by TaylorMade features an Anti-skid Groove System Insert (ASGI), which drastically reduces skid and bounce, dampens impact vibration, and promotes precise line and optimum speed control - the result is better performance on the greens. In fact, 88% of golfers who tested the Rossa putters had a measurable decrease in backspin and a marked increase in forward spin.
